Answer 1

1.Concentration of salt solution is hypertonic solution (water concentration lower as compared to the cell) therefore it causes exosmosis.The outward movement of water from the cell result in irritation and excessive dehydration.This result in reverse movement and hence person start vomating.

2.Our skin is porous and behaves as a semi permiable membrane. When we wash clothes, our hands are exposed to water for a long time. Our hands behave as hypertonic solution and the outside of our hands behave as hypotonic solution. Hence, water flows from high concentration to low concentration. The water is not entering your hands, it actually leaves them and hence, they shrink.

3.When salt is applied to vegetables, it creates a higher ion concentration at the surface than exists deep within the cells. To equalize the concentration levels, the water within the cells is drawn out through the permeable cell walls by the process of osmosis.




In short answer of all the question is osmosis
